Two ear files have the same session bean class name, for example, @Stateless @LocalBinding(jndiBinding="StudentManager") @Local(StudentManager.class) public class StudentManagerBean implements StudentManager { ... } When deploying the two ears, get the jndi name conflicts. java.lang.RuntimeException: org.jboss.ejb3.common.registrar.spi.DuplicateBindException: Could not register org.jboss.ejb3.proxy.factory.session.stateless.StatelessSessionLocalProxyFactory@100c676 under an already registered key, "ProxyFactory/StudentManagerBean/StudentManager" If I change the binding annotation in one ear as the following: @Stateless @LocalBinding(jndiBinding="StudentManager1") @Local(StudentManager.class) public class StudentManagerBean implements StudentManager { ... } I got the same error message. How to solve the naming conflict if we keep the same class name? Thanks. Dave View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4247182#...
